I made an electric blast that gets bigger when you equip, then click with the tool.
It does get bigger, but it just falls through the ground.
This script is a regular script inside the tool (And be sure to read the green comments):
function onClick() script.Parent.Handle.Size = Vector3.new(30,30,30) script.Parent.Anchored = true -- After first test, I tried adding this, but nothing really changed. end script.Parent.Activated:connect(onClick)
